3d printing with metal on your own desktop 3d printer! This amazing one of a kind filament will allow you to print with actual copper at home! Straight from the printer parts look almost laser sintered with a matte finish. With a bit of sanding and polishing the copper particles will start to shine and shimmer unlike any 3d printing filament you have seen before. The weight of the material is something special, about 3 times heavier then our regular PLA/PHA.
